"Sending love Demi. I've relapsed many times. The recovery community has always welcomed me back with infinite love and support. Always here for you. One day at a time," Macklemore said. Baldwin posted several heart emojis.

Lovato, on Sunday, thanked her family and fans for their support. "What I've learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet," she said.

"To my fans, I am forever grateful for all of your love and support throughout this past week and beyond. Your positive thoughts and prayers have helped me navigate through this difficult time. I want to thank my family, my team, and the staff at Cedars-Sinai who have been by my side this entire time. Without them I wouldn't be here writing this letter to all of you," she continued.
